VEHICLE-SPRING.

Specification of Letters Patent.

Application filed February 2, 1920. Serial No. 355,723. v

To all whom t may concern.'

Be it known that l, JAB/Ins A., LUKE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vehiole-Springs, of which the following is a specification.

rlhis invention relates to springs, and more particularly to that type of spring used for motor propelled vehicles and has for its object to provide a type of construction whereby the wheels of the Avehicle may be secured to the body thereof in such a manner as to prevent sudden shocks or lifts of the wheel being transmitted to the body.

Further objects of the invention are t0 provide a construction of spring which will lend itselfI readily to road inequalities, and one which will easily absorb such irregularities before they reach the body of the vehicle, and the construction of a spring which will be simple, free from extra or superfluous parts and very durable and efficient.

Further objects of the invention are in part evident and will appear in part more clearly in the following description and claims.

Reference being had to the accompanying drawing wherein like reference numerals indicate similar parts of reference throughout the various views and wherein Figure l is an elevation of a spring constructed in accordance with the principles above set forth and Fig. 2 is a sectional end elevation of Fig. l.

The invention consists principally of a pair of spring members l() and l2 which occupy positions upon each side of an axle 13 and which are secured to the vehicle body by means of the U-bolts let and l5 the ends of which pass through the framework of the body and are secured in place by means of nuts as is customary in this type of spring. As usual in this type of'spring the lower leaf i6 terminates at its end in eyes 17 through which are inserted the lower bolts 18 of shackles i9. rlfhe upper end of said shackles have secured to them by means of bolts 20, suitable clevises 2l, which are in turn carried upon the ends 22 and 23 of yokes 24E rotatably secured upon the axle housing 25. The yokes 24 are prevented from any longitudinal movement upon the axle housing by means of shoulders 26 and collars 27 placed at each side thereof.

Upon referring to Fig. 2 it will be seen that theV arm 22 of the yoke 24 is considerably longer than the arm 223, and in this manner any slight shocks due to irregulari` ties in the road surface are suilicientlytaken care of by the spring l0 due to the greater leverage upon the yoke 22. In this manner the bolts 30 actas a center for the axle to ride upon. Should the shock be too great it is immediately absorbed by the spring l2 and a rocking motion transmitted between the two springs thus absorbing the shock sufficiently before it is transmitted to the vehicle body. The springs therefore assist or work against each other in absorbing the shocks.

Obviously the device is capable of various modifications and l do not wish to limit myself in the construction of the same further than is required by the state of the art or that which comes within the scope of the appended claims.

I claim:

l. ln a vehicle, the combination with a vehicle axle, of a pair of leaf springs placed respectively along opposite sides of said axle, and a lever fulcrumed on the axle and connected at its opposite ends to adjacent ends of each spring.

2. ln a vehicle, the combination with the vehicle axle, of a pair of leaf springs adapted for connection at the middle thereof to the vehicle body, and a lever at each end of the springs, each lever being fulcrumed on the axle and connected at its opposite ends to the adjacent ends of the respective springs.

3. In -a vehicle, the combination with the vehicle axle7 of a pair of leaf springs adapted for connection at the middle thereof to the vehicle body, and a lever at each end of the springs, each lever being fulcrumed on the axle and connected at its opposite ends to the adjacent ends of the respective springs, the arms of said levers being unequal in length.

l. ln a vehicle, the combination with the vehicle axle, of two springs located respectively at opposite sides of the axle, and a lever fulcrumed on the axle and connected at its opposite ends to the springs respectively.

5. In a vehicle, the combination with the vehicle axle, of two springs located respectively at opposite sides of the axle, and a lever fulcrumed on the axle and connected at its opposite ends to the springs respectively, the arms of said lever being unequal in length.

6. ln a vehicle7 the combnatenlvwththe vehicle axle, of two springs at opposite sides of the axle respeotlvely7 and means coni nectlng the springs and axle to transmlt unrespectively.

7. In a vehicle, the combination With-the vehicler` axle', -of' a" pair* of leaf springs at opposlte slcles thereof', and. Cross levers con-- meting-adjacent enclsfof tlne'sprngs,y said vlevers belngpwotecl upon'the axle.
